Annotations for scala class to use mapper

Question

I am using DataStax driver to connect to Cassandra database from my Scala application. The driver comes with com.datastax.driver.mapping to map the database table to the corresponding entity class.

I intend to use the mapper like this:

def SelectOperationUsingMapper()={
try{
  val session = cluster.connect()
  val manager = new MappingManager(session);
  val mapper = manager.mapper(classOf[User])
  val result= mapper.get("@ned")
  print(result.Name)
}
finally{
  cluster.close()
}

}

The Entity User is mapped to the database using @Table annotation like this:

abstract class BusinessEntity

@Table(keyspace="MySpace", name="User")
case class User(userId:String, emailId:String, name:String, description:String, password:String, country:String, joinedDate:Date) extends BusinessEntity{
  @PartitionKey
  @Column(name = "UserId")
  val UserId= userId
  @Column(name = "EmailId")
  val EmailId= emailId
  @Column(name = "Name")
  val Name= name
  @Column(name = "Description")
  val Description= description
  @Column(name = "Password")
  val Password= password
  @Column(name = "Country")
  val Country= country
  @Column(name = "JoinedDate")
  val JoinedDate= joinedDate
}

I receive a error message saying No getter or setter method found for Field UserId.

I found an example java code for the similar annotation example and it works fine:

 @Table(keyspace = "accounts", name = "users")
public class User {  
    private int id;
    @Column( name = "account_id" )
    private int accountId;
    private String name;
    @Column( name = "creation_date" )
    private Date creationDate;

My doubt, is there no way to use the @Table annotation in scala code? If yes, where did i go wrong?

PS: I tried implementing the case class user without body and providing the annotations on top of parameters. Even that gave the same error message.
